The Wärtsilä degaussing system "DEG COMP MOD 2" is versatile, suitable for deployment on all classes of naval vessels. It is capable to compensate the permanent induced and eddy current magnetic interference fields of naval vessels to specified target signatures. It´s non magnetic design allows deployment also on Mine Countermeasure Vessels (MCMV) and on non-magnetic submarines.
The heart of the system is the computer-based Degaussing Control Unit (DCU), which accommodates the MMI and interfaces to the other main system components. For control and monitoring, standard interfaces are provided.
In comparison to conventional degaussing systems the Wärtsilä degaussing system DEG COMP MOD 2 offers the following system inherent advantages:

Degaussing Control Unit
Heart of the system is the computer based Degaussing Control Unit (DCU), which accommodates the MMI and interfaces to the other main system components. For control and monitoring, standard interfaces are provided.
In automatic mode the DCU receives the actual magnetic earth field data either from the magnetic probe system or by calculations derived from a geophysical model as data base and inputs from the vessels´ navigation system. To this end the DCU is equipped with a suitable memory, which contains the algorithms of the geophysical model for generation of the magnetic earth field data. In emergency mode the navigation data can be input manually.
At any given moment the system automatically calculates the required sum current for each degaussing coil, which is composed of the permanent-, induced- and in it´s maximum configuration also the eddy current content.
On the basis of this calculation each degaussing power amplifier generates the required DC sum current to feed the related connected coil. Menu controlled interactive communication between the user and the DCU is effected via a display with attached keyboard and functional softkeys. Error messages are generated in case specified limits are exceeded, or undesired operational conditions prevail.
Power Supply Unit
Depending on the respective type of vessel the "DEG COMP MOD 2" system makes use of two different coil supply concepts:
Both power supply concepts use a family of current controlled amplifiers of different configuration and power rating, each suitable for the direct supply of the respective sum current to the connected degaussing coil.
Intelligent Terminal
The Intelligent Terminal provides features for magnetic signature prediction of the vessel to the ship’s command according to the actual operational conditions. The Intelligent Terminal can be employed together with Wärtsilä SAM’s degaussing system technology "DEG-COMP” or as a "stand-alone” equipment.
The Intelligent Terminal is designed for the following operational modes:
